This converter provides two way RS232 serial communications signal conversion between the TTL (Transistor Transistor Logic) output (from an OOPic or other PIC) to and from a personal computer RS232 serial COM port.  This converter can be used on any Micro controller/PIC which has TTL serial communications that needs to be converted to RS232.

These cables are 3.3V TTL signal converters.  The cable converts 0v & (3 to 5v) nominal TTL signal to –12v & 12v RS232 serial signal.  These cables require 3.3V (3 to 5v)  power from the TTL side to operate.  The cable is 72 inches long and has a type 2 TTL connector.  See our support page for details on the TTL connectors.

The RS232 serial cable with voltage level converter comes completely assembled.  The circuitry is built into the cable. 

For further details, downloads, and instructions see our RS232 page.

The RS232 to TTL level converter serial cable is available in two cable lengths and multiple connector configurations. 

We sell different Types of Cables/Connectors. This is a Type 2 connector.

 Type 2: RS232 to TTL signal converter serial cable (Tx, Rx, +5, GND).  It is a serial cable with two 2-pin connectors for use with the existing 40 OOPic I/O header or other PIC pinouts.  This type does not have handshaking.
